 /**
  * Standard workbench wizard for importing resources from a zip file
  * into the workspace.
  * <p>
  * This class may be instantiated and used without further configuration;
  * this class is not intended to be subclassed.
  * </p>
  * <p>
  * Example:
  * <pre>
  * IWizard wizard = new ZipFileImportWizard();
  * wizard.init(workbench, selection);
  * WizardDialog dialog = new WizardDialog(shell, wizard);
  * dialog.open();
  * </pre>
  * During the call to <code>open</code>, the wizard dialog is presented to the
  * user. When the user hits Finish, the user-selected zip file is imported
  * into the workspace, the dialog closes, and the call to <code>open</code>
  * returns.
